Employment Agreement between Teradyne and Edward Rogas, Jr.



 Exhibit 10.39 
  
 EMPLOYMENT AGREEMENT 
  
 In consideration of my at-will employment by Teradyne, Inc., a corporation of the Commonwealth of Massachusetts (herein referred to as “the Company”), and the
payments made to me as consequence thereof and specifically the grant of an option in 2004 to purchase common stock of the Company, I agree that I will promptly report to an officer of the Company or to such other individual as may from time to time
be designated, all inventions and new ideas (“Inventions”) which I, alone or with others, have conceived or reduced to practice since the time of entering the employment of the Company in respect to any subject matter relating to the
business in which the Company is engaging as of the date of conception or reduction to practice of each such invention or new idea. This obligation ceases with termination of my employment with the Company. 
  
 I further agree to assign to the Company the entire interest throughout the world in all
Inventions referred to in the proceeding paragraph, whether or not reported by me, to the maximum extent permitted by Section 2870 of the California Labor Code. I also waive all claims to moral rights in any Inventions. I understand that the
provisions of this Agreement requiring assignment of Inventions to the Company do not apply to any invention which qualifies fully under the provisions of California Labor Code Section 2870 (attached hereto as Exhibit A). I agree to advise the
Company promptly in writing of any inventions that I believe meet the criteria in Section 2870. I also agree to execute all papers and do anything necessary and reasonable to secure to the Company title in any Invention and Letters Patent pertaining
thereto including the giving of testimony in any suit if called so to do during or after my employment but all at the expense of the Company. 
  
 I further agree that I will make a written record of all inventions and new ideas falling within the scope of this agreement in the form of notes, sketches, drawing, or
reports relating thereto, which records shall be and remain the property of and available to the Company at all times. 
  
 I further agree that I will not, during or after the period of my employment with the Company, divulge to any unauthorized persons confidential information concerning the
Company’s business, technology, and activities that I learn during the period of my employment, or use any such information except on the Company’s behalf. 
  
 I further agree that I will observe all rules and regulations laid down by the Government agencies relating to the safeguarding of
classified information that may be disclosed or entrusted to me in connection with any contract between the Company and the Government or any contractor with the Government. 
  
 I further agree that I will not, during the period of my employment by the Company, directly or indirectly enter the employment of, or
render any professional services, including but not limited to as an independent contractor, consultant, director, partner, owner or otherwise, except such as are rendered at the request of the Company, to any individual, partnership, association or
corporation who or which is a competitor of the Company without the prior permission in writing of the Company. Competitor includes, but is not limited to, any business or enterprise that develops, designs, produces, markets, sells or renders any
product or service or intends to do so that is competitive with any product or service developed, produced, marketed, sold or rendered by the Company, including actual or demonstrably anticipated research or development. I further agree that I will
notify the Company of any outside employment in which I am engaged during the period of my employment with the Company. 
  
 I further agree that during the period of my employment with the Company, and for a period of one year after my employment ceases for any reason, I will not (except on
the Company’s behalf) solicit (for the purpose of providing a product or service that is competitive with the Company) any customer or prospective customer of the Company that was contacted, solicited or served by me within the five year period
immediately preceding the termination of my employment with the Company. 
  
 I
further agree that during the period of my employment with the Company, and for a period of one year after my employment ceases for any reason, I will not recruit, solicit, hire, or engage as an employee or an independent contractor, any employee or
former employee of the Company, excluding former employees whose employment with the Company has been terminated for a period of six months or longer. 
  
 Due to the global market in which the Company operates, the geographic scope of this Agreement shall extend to anywhere the Company or its subsidiaries do business, have
done business or have plans to do business. 
  
 This Agreement supersedes all
previous agreements between me and the Company relating to the subject matter hereof, and may not be modified on behalf of the Company in whole or in part except by a statement in writing signed by an authorized officer of the Company. 

 
 I further agree that if any one or more provisions in this agreement are deemed
unenforceable, they will be reformed to the extent necessary to make them enforceable, and the remaining provisions of the agreement will continue in full force and effect. 
  
 I further agree that this Agreement shall be governed by and construed as a sealed instrument under and in accordance with the laws of the
Commonwealth of Massachusetts without regard to conflict of laws provisions. Any action, suit or other legal proceeding that is commenced to resolve any matter arising under or relating to any provision of this Agreement shall be commenced only in a
court of the Commonwealth of Massachusetts (or, if appropriate, federal court located within Massachusetts), and I consent to the jurisdiction of such a court. 
  

I acknowledge that I have carefully read this Agreement and understand and agree to all the provisions in this Agreement.

 Exhibit A 
  
 CALIFORNIA LABOR CODE SECTION 2870 
  
 INVENTION ON OWN TIME – EXEMPTION FROM AGREEMENT 
  
 (a)        Any provision in an employment agreement which provides that an employee shall assign, or offer to assign, any of his
or her rights in an invention to his or her employer shall not apply to an invention that the employee developed entirely on his or her own time without using the employer’s equipment, supplies, facilities, or trade secret information except
for those inventions that either: 
  

	 	(1)	Relate at the time of conception or reduction to practice of the invention to the employer’s business, or actual or demonstrably anticipated research or development of the
employer, or 

  

	 	(2)	Result from any work performed by the employee for his employer. 

  
 (b)        To the extent a provision in an employment agreement purports to require an employee to assign an invention otherwise
excluded from being required to be assigned under subdivision (a), the provision is against the public policy of this state and is unenforceable.
